WASHINGTON (AP) - Public health officials are warning travelers and workers present at four U.S. airports on two recent days that they may have been exposed to measles from a traveler arriving from London.

Authorities said Saturday that a New Mexico woman later confirmed to have measles arrived at Washington Dulles International Airport late in the afternoon of Feb. 20. Two days later, the measles-infected traveler departed from BWI Thurgood Marshall Airport near Baltimore on an evening flight to Denver, Colo., and then on to Albuquerque, N.M.

The traveler became sick and was subsequently diagnosed with measles in New Mexico, said Tom Skinner, a spokesman for the Atlanta-based Centers for Disease Control and Prevention. He said Saturday night that authorities in those states are trying to notify travelers who sat close to the infected passenger on the flights.
Not sure if this escalates to the level of "shtf event" but wanted to pass the news along. It would blow to get the measles as an adult.
